which is bored out, as at 37, from each end;

and through Vthis'bored-outv portion, at the inner end thereof, a pin 38l is (passed to which Y theoinner end'of the spring 36 projecting into Y said shaft, isse'cured. v .The inner end ofthe spring 3,6.V is thereforel ax-iallysecured to, and Withinthe shaft, and the outer end thereof is secured to theknife carrier in substantial alinement.axially With said shaft when the `knife carrier is retracted by the spring..

`will appear hereinafter.

Adjustably.supported from each end Wall 12 is a guard in the fornrof a plate 39, Which also serves as an actuator for theV cutter or :Coring knife, andas part of a housing for cn- 4 iclosing the rotatable head 18 andthe knife Walls 12.:V Y,

.Between the guard" or actuator and the end vall 12 of the framelO, spiral springs 42 f are disposed, which surround the bolt-SV40, and keep the guard plate39 spacedv a. definite distance from said end Wall. The bolts 40 are slidable through the openings 41 in the end Wall 12 and have stop nuts 43 ythreaded Vthere'onto 'so as to bearagainst the inner surface V-of said end Wall and t-hus prevent the outward travel of the guard or actuatorv beyond the position predetermined therefor.

'fee

The exact position of the guard or actuator lmay be varied #by adjusting the nuts 43y on lthelooits' 40.

The spacebetvveen the ,guard plate and v. Y. the end Wall 12 ofthey frame Y10 yis enclosed atgthe sides andtop by a substantially U- 39 is a'Wear annulus 46, Which'is riveted or otherwise fastened thereto git being preferably constructed of hard Vmaterial, and against it is adapted` tobear the lstop screw r33, this Astop screvvY beingpressed thereand ,consequently :When vthe'4 knife-carrying head18 is beingrotated, thefstopV screw 33 travels circularly and in contact Withi the Wear annulus 46. y; f L Y The tomato or other article tobe cored, shown lforexampleby the dotted lines in Figs. 1 and 5 and designated by the numeral 47, is vplaced againstthe outer side of the guard or actuator 39 With its center or axis in alinement or substantially in alinement With the axis of the opening 45; andthrough the medium of the tomato or 'other article to inwardly against the action of the springs 42, causing 'the bolts 40 to slide through 'the vbe cored, 'the guard-or actuator 39fis forced openings 41 in ltheend Wall12 of the frame.

.During'this action, the knife carrying head 18 is in rotation, causing theknife to travel eircularly and at the same timeV to move out-v wardly' through Vthenvopening 45, swinging on lthe pivot 25 'as itsy center, ,-Thus, While .entering the tomato or other article,y it is .gradually being Vmoved toward the axis of the article, as indicated inFigL 5. The tomatoor other article is held against rotation by the operator, and'due to the fact that the knife is traveling in substantially a lcircular "path While beingforced outwardly, the core Will therefore beapparentthat the operation of coring a tomato is quick and certain, and that it can beV most efliciently accomplished by inexperienced help. Removingthe tomato socored from the guard plate-,permits the `springsr42` to lreturn the guard or actuator to normal position, Whichrposition is determined by the stop nuts 43-on the bolts 40. v

For the purpose of( limiting the inward movement ofthe guard orV actuatoig'vve'have` provided two. stop screws 49, these being threaded through the end Wall 12 of the frame. 1() `from the inner side thereof, and the spacing of `thejouter end of these stop `screws from the Wearl ring 46 on the inner side of theY guard or' actuator determines the` range of movement ofthezlatter; sufficient movement only of said guard or actuator Y rvments to.limitthe'movement` of saidguard -away Vfrom said end wall, stop means on said 8.
